The US cities hit by the housing crisis—with the notable exception of New York—are disproportionately dominated by single-family homes, enforced through explicit zoning laws. Being "some of the densest places in the US" does not mean much when the entire country outside NYC is so sparsely populated! SF is the second-densest "large" city in the US. I haven't found specific numbers, but looking at zoning maps at least 50% of the residential space is zoned for single-family homes only, with the majority of the remainder explicitly zoned for low-density residences. A big chunk of the city is basically a suburb! The rest of the Bay Area, of course, is more like 90% single-family housing. This year Berkeley passed a resolution removing single-family zoning throughout the entire city so perhaps the tides are shifting, but even if zoning laws and politics change, it'll take decades for this to meaningfully affect the housing supply.
